very slow, crashing desktop

Tue Jul 24, 2012 8:36 am

Hello.
I just got my RPi and installed Raspbian a few days ago. I notice that the desktop system is very slow: every time I try to do something the CPU goes 100%, windows need like 10-20 seconds to open and the system eventually hangs if I open a few programs.
Right now I had aMule and Transmission opened, and also Midori with a few tabs, and was barely manageable; after I added a torrent file and it begun downloading (to an external HDD) at 800 KB/s aprox. the CPU when 100% all the time and crashed. Am I making it work too much?
My root partition is mounted in an external HDD, so I don't think is a problem with my class 4 SDHC.
Could it be a power problem? Right now the RPi is getting only 500mA from a DUB-H7 hub, until a buy an Y-cable.
Thanky very much.

You are pushing your RPi far beyond reasonable expectations. It is not a desktop computer.

You could help the situation by using chromium instead of Midori, and open only one tab at a time in the browser.

You are running out of memory - all the stuff you indicate will be using a lot of memory. That won't cause a crash though -that more likely to be the power supply.

You are expecting too much from a low end processor with limited memory I'm afraid.

Ok, I'll test the RAM.
